Battleground #4

In the tense waters of the Pacific, a lone U.S. submarine, renamed "Revenge" in defiance, sets out to track down the enemy vessel that has crippled American shipping. With courage and grit, the crew faces relentless danger as they pursue the elusive Sakawi through treacherous seas.

In "Torpedoed!", a U.S. destroyer is caught off guard by a coordinated attack from a Chinese submarine and destroyer, leaving the Invincible crippled and listing in the water. With the ship damaged and the odds stacked against them, the crew refuses to surrender or abandon ship, rallying to make emergency repairs and prepare for a daring counterattack.
